By this point you should have a fairly good understanding of how HTML works and how a web page goes together. Java Script should not be attempted until you have a fair understanding of HTML. If you are new at HTML or feel that you have not had enough pr actice, you can go back to section on HTML. After you get the hang of it, come back and try Java Script.

Java Script, like CGI, will add another dimension to your web page. It is not easy to learn. If you know anything about programing it will be helpful. If you have not had any programing experience be patient and don't try to go too fast. Come back to a section or reread a section if you need to. Even if you have had some experience in programing, unless you have used an object oriented language, you may find Java Script confusing. Java Script is based somewhat on C and C++. In any case, good luck i n your endeavor and have fun. We have tried to give you a detailed explanation of what everything is. I hope you enjoy it.

Since their beginning, web pages have become more and more complicated. There have become new ways to accomplish jobs. One of those is Java Script. Java Script is a programing language. It differs from HTML in that HTML tells a browser how to display text, while Java Script takes input from the user and processes it. Java Script does some of the same jobs as CGI except that Java Script is run on the users home computer through the browser instead being run on the server. This cuts down on network tr affic and allows for faster processing time. Java Script shares some of the same functions with CGI, but not all. In your web page it may be necessary to use either Java Script, CGI, or both to accomplish your goal.

In surfing around the Web, you may have heard about Java. Java is not exactly the same as Java Script. As its name implies, Java Script is a scripting language. It is used in web pages to check and process data inputted by the user or the web page. Ja va on the other hand is a true programing language. It is designed to write programs for all platforms (IBM, Mac, Unix, OS2...). Java can't be run on your browser. It is like C++ and Basic. Java Script on the other hand is designed to be run by your br owser. Java Script cannot be run on your personal computer without your browser. It requires your browser to interpret it and execute the code. Not all browsers support Java Script. If you want to run Java Script you must have the most recent versions of either Netscape Navigator or Microsoft Internet Explorer. Most other browsers, like Mosaic and the text based browser known as Lynx, do not support Java Script.
